### PRODUCT DESCRIPTION

Looking for a Valentine's Day Activity that incorporates science, technology, engineering, and/or math?

The "M" in this STEM challenge should be an extra-large capital letter, because it is definitely the focus in this 2-D challenge!

The basic premise:
Individually or in partners/small groups, students will design the “heaviest” heart possible.
– Using a criteria/constraints list, students create small hearts of various colors & sizes. Point values are assigned to each color group based on its size. Students arrange various configurations of their smaller hearts inside a large, outer heart in order to create the “heaviest” possible heart. (“Heaviest” is in quotation marks because we are not measuring weight; rather, we are assigning point values to inner hearts.)

This challenge can be run simply (focusing on shape creation & manipulation, measurement, addition, and symmetry), or you can add complexity (focusing on length/width ratios, multiplying & dividing decimals, percent contribution, etc.). Two criteria/constraints lists are provided to highlight either end of the spectrum along with editable versions.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Benefits of this STEM Design Challenge:
- Focus on critical thinking, problem solving, and application of learning
- High levels of student engagement
- The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)
- Highly flexible and differentiated for materials, timing, grade levels, and rigor.

Depending on the complexity you select for the Criteria & Constraints list, each design iteration should be planned for at least 60 - 90 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly. I recommend working on STEM Design Challenges in multiple iterations to get the full value.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Materials you’ll need to do the activity are easily modified.

Sample/suggested materials for each student or group:

– Colored construction or printer paper (3 – 6 sheets)
• Recommended one sheet each of red, pink, and purple per partner/group
– Colored pencils or crayons
– Scissors
– Rulers
– Heart outline copies
– Design analysis handouts
– Optional
• Folders, Ziploc bags, or large envelopes to contain cutouts if using on multiple days.
• Glue (if you want students to glue their final design in place)
• Calculators (for younger students and/or those with special needs)
